Doctor halts brutal marsh child experiment

The Doctor intervenes as Dexeter begins an ethically abhorrent surgery on a captured marsh creature in the Science Unit. When Romana screams in response to the creature’s pain, the Doctor furiously attempts to stop Dexeter, exposing the human alliance’s moral rot. The restraints fail and the creature breaks free, strangling Dexeter before wrecking the lab. Though the Doctor saves himself from the creature’s violent reach, he later turns his fury on the Deciders, shattering their veneer of authority by revealing their ship has sat idle for centuries—a damning testament to their failed leadership and hidden stagnation.
